WINDOW- SCREEN.

SPECIFICATION forming part of Letters retent Ne. 5o7,s44, 1etea oetober31, 1893.

Application le'd April 21,1893.

.To all whom t may concern,.-

Be it known that l', JEROME RICH, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented certain new and useful Improvements in Window-Screens, ofwhich the following is a specification, reference bein-g had therein tothe accompanying drawings.

The invention consists in the peculiar construction, arrangement andcombination of the various parts as more fully hereinafter described.

In the drawings, Figure lis an elevation of a window frame showing myscreen in position partly in section. Fig. 2 is a cross section on lineaz, Fig. l. Fig. 3 is an enlarged perspective view of the lower edge ofthe screen. Fig. 4. is a cross section on line y y in Fig. l. Figs. 5and 6 are views illustrating the manner of constructing the screen.

My screen belongs to that class in which the wire cloth is secured to aroller at'the top of the window frame and adapted to be wound thereon orunwound therefrom in raising or lowering the screen. In the use of suchscreens heretofore it has been found necessary to use a spring roller toraise the screen, and it has also been found necessary to prevent thebagging or sagging of the screen to provide means at the edges forpreventing the withdrawal laterally from the guides of such edges. Myinvention enables me to dispense with the spring roller and also todispense with the securing devices for the edge of the screen. I havefound that by winding the screen on the rollerunder sufficient tensionor pressure to give the wire a permanent spiral set it will practicallyact as its own spring for raising the screen and winding it about theroller and by making a rigid frame for the lower edge of the screen itenables me to dispense with the securing devices for the edges.

A is the window frame. B are brackets at the upper end thereof securedat each side. C is a roller journaled in said brackets.

I) is a hood of substantially circular shape, as shown in Fig. 2 and'having the flange or plate E extending across the window frame in rearof the roller.

F are standards or strips secured to the inner face of the window frameand having groovesGon their inner edges. These strips Serial No.471,265. (No model.)

are bifurcated at their upper ends to receive the lower end of thebracket. The screw H passes laterally through the bifurcation and intothe bracket as shown in Fig. l, thus enabling me to secure the bracketin position upon the frame with a minimum of screws in the wood-work.

I is the screen. In securing this screen upon the roller I first securethe upper edge of the screen to the roller and then secure the roller ina suitable rotary socket having a crank handle J, as shown in Fig. 5.Upon the screen I 'then place a weight K, or apply spring pressure, orin any other way holding it under pressure, While I wind the screenabout the roller, so that it will be wound about the roller with sucienttension to impart a permanent spiral set to the screen. To aid in this Iin- Sert the screen when wound about the roller into a clamp or socketL, as shown in Fig. 6 and allow it to remain a sucient time to becomepermanently set in its spiral form.

The lower edge of the wire I secure in a rigid metallic frame,constructed preferably as shown in Figs. 3 and 4 and consisting of thecross-bar L and the guide strips M at the ends of the cross-bar. This Ipreferably make of tin or other suitable sheet metal, folding the tindouble to form sockets in the top of the cross-bar and the inner side ofthe guide strips into which the lower edge and the lower end of the sideedges of the wire cloth are adapted to be engaged.

To secure the cloth in the cross-bar I preferably double it upon itself,as shown in Fig. 4., by making the loop or bend N. The frame thusconstructed engages in the slots or grooves Gof the strips F and formsthe means of guiding the wire cloth in its vertical movement. Ipreferably secure the cross-bar L in a wooden cross-bar O, securing itin a slot P therein, by means of suitable screws, such as Q. I havefound that this structure makes a rigid frame for the bottom of thescreen; that no means are required for guiding the screen at the edgesto prevent its sagging or bagging and that by forming the screen with apermanent spiral set about the roller a plain roller may be used withoutany spring, and the screen will naturally coil itself about the rolleras it is raised.

By using the strips F on the outside of the IOO Window frame it isevident that my screen may be attached to any Window Without changingthe frame, except by the addition of these strips, which may be readilyremoved when desired and which do not detract at all from the appearanceof the frame. In fact the structure is ornamental and may be left inplace Winter and summer.

What I claim as my invention is- 1. In a window screen, the combinationof the roller, the wire cloth secured at one end thereto and woundspirally about the roller with a permanent spiral set, substantially asdescribed.

2. In a Window screen, the combination of the roller, brackets in whichthe ends of the roller are journaled, the wire cloth secured at one endthereto and Wound spirally about the roller with a permanent spiral set,and strips at `the sides of the screen, having guide Ways in which theedges of the screen engage, substantially as described.

3. In a Window screen, the combination of the roller, the screen woundspirally thereon, strips having guide grooves with which the edges ofthe screen engage, and a rigid frame extending across the lower end ofthe screen and a short distance up the sides thereof, substantially asdescribed.

4. In a Window screen, the combination of the roller, the screen Woundspirally thereon, the strips at the sides having guide grooves on theirinner edges with which the outer edges of the screen engage, and a rigidframe at the lower end of the screen, consisting of the cross bar L, thevertical end bars M secured to the ends of the cross-bar, and to whichthe screen is secured, substantially as described.

5. In a Window screen, the combination of the roller the screen Woundspirally thereon, the strips having guide grooves with which the edgesof the screen engage, and the rigid frame at the bottom of the screensliding in the grooves and composed of sheet metal bent around the edgesof the screen secured thereto and comprising the cross-bar L and thebars M, substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.

JEROME RICH.
